To all whom it may concern: c

Beit known that'we,1LEwis D.-CRTRIGHT, of Hyde Park, Cook. county,Illinois, and S'rE- PEEN P. DaRLINGmNpf'West Chester, county 5- 01'Chester, and State of; Pennsylvania, have invented .a new and usefulImprovement-in Metallic Boofing-Plates or Shingles, of which thefollowing is a true and exact description,-

due reference being bad to the accompanying drawings, which form a parthereof.

. Our improvement has especial reference to roofing platesof ,thekindwhich are adapted to be secured to'the roof by beginning to lay.

them'at the comb andworking downward to the caves; and the object of ourin v'gentignistg. make-snelrshi-ng'les' more thoroughly water tight thanhas heretofore been the case, and guard against the danger of the watergetting theblank from which the shingleis formed through the metallicsheathing.;- Someof our improvements are, however, also capable ofuseful application with metal shinglesof the ordinary types, which aresecured to the roof,

beginning-at the eaves and'contin'ued in' overlapping layers to thecomb.

Reference being now had to the drawings which illustrate ourimprovements, Figure 1 isa plan'viewof-four of our improved shinglesinterlocked together asthey are secured upon. the roof; Fig.2, asection. throughthelowerjcorner, ofoneof our shingles on the-line z z-ofFig. 1;" Fig.3, a cross-section of one of ,the shin'gleson the line 3 yof Fig. 1; Fig. 4, a cross-section of the joint of two interlockedshingles, of Fig. 1; Fig. 5, a'crosssect1on of the oint of two shinglessituated one vertically over the other, as on the line 10 w of Fig. 1.Fig. 6 15 a back view of one of our improved shingles. Fig. 7 is aperspective view of three shingles .49 grouped as in Fig.1, with theupper one re moved. Figs. Sand 9 arecuts of the blanks out of which ourimproved shingles are made,

and Fig. lO is a view similar to Fig. 1, show- -ing another way in whichthe shingles can be 5 interlocked and secured upon the roof.

' A, B, O, and D are fourof our improved metallic shingles constructed nwhat we be lieve to be their best form.

taken, for instance, on the line a: x"

E E are the two upper edges of the shingles, 1 in which'is formed thedepressedQgutter E, F being theextreme outer-edge,0f-;the sheet formedinto a downwardly-bent flange extending obliquely from the top of thegutter down toward the plane of its bottom.

e is the extreme top oftheshinglejwhere the gutters E E run into eachother, and which we prefer to cut oil ina horizontal line, as

shown, for reasons hereinafter explained.

' FF are the two lower-edges ofour shingles. They are bentso asto formthe fold f and nailing-flange F, the edge of the fold beingalso bentover to fqrm the hook-like'edge' F... The ggepthnfithjenfoldfsheuld-besuehas toenable it to contain the whole of the g-utter E asis I 5.

being so cut atthis point that the metal bent back-to form the folds fon the two adjacent edges shall not interfere or lap the one upontheother. I

' We prefer to cut the metal blank, as'shown.

The lateral corners f f of the; blank arepreferably cut away, as shown,'=so that',the ffold f shall not extendunder thedepressed gut;

. soldered to the bottom of the shingle, the bottom corner of which,when finished, isbest shown in Figs. 2 and 6.

In applying these shingles toa roof they should be laid from the top0r-co1nb downward in horizontal layers or rows, and prefer; ablyslightly staggered, as shown in Fig. 1, although their edges may be madetoregister,

as in Fig. 10, if desired; The edges E E of each shingle are thrustinto. the flanges ff of the'two adjoining shingles in the row above,

E being to facilitatethe entrance of the edges E under thedownwardly-bent edges F of the fold f, and the sides of the gutters Earemade with a divergent incline, as shown, soy-thatthe edge "1 of the foldmayslide up'out ofthe gutter and rest on the surface of the lowershingle whenr'it'is pushed home, as shown in Fig. 4, the natural springof the metal-causing the edge F to form afclose and tight con-.

tact with the surfaceof the shingle upon which it rests. In forcing thelower shingle into place its upper corner, 0, passes under the lowercorner, a, of the shingle vertically-above it and over the piece G, whenit is used, the horizontal edge of the corner e registering or nearly'registering with the horizontal line between the corners a a of theshingle above when the shingles are staggered.

At each corner the lower point, a, of a shingleis raised from the roofby the thickness of the shingle immediately below it and that'of thelateral shingles, which are thrust between the lower and-upper shinglesat the corners.

The point a would therefore naturally be sep-' 1 with each othe'r,thecombinationof 'thelad-v arated from. the shingle below by a distanceequalto the-thickness of the edges of the lat- "eral plates, but thisdistance we diminish by bending down the points a, as shown in Fig. 5.

As will be seen, we secure by our construction a tight jointhetween theedges F of the upperv shingles and the surface of the lower ones,andavoid the continued contact or close approach of the metal 'edges andfoldstforming the joints, thus avoiding the capillary action,

, whichhas been found to have a strong tendencyto' cause such joints toleak. Any water passing beyond this joint is caught in the gutters E,whichlead itonto thesurfaces of the lower shingles, (see Fig. 7,) andif, by reason of capillarity or other cause, any of the water escapingfrom the gutters. shouldworkupward on the shingle ou'which it empties,it is intercepted by the gutters on its upper edges, 'which guttersmaybesaid/ to be interlocked with the guttersof the upper shingles.

,We consider the'piece G .as a, convenient.

addition to our shingle, but it is not essential,

- and even'when, used-need not necessarily be soldered at g, asshown. fThe form of the blank may also bechanged atany or all of its corners inmany ways. Thus, 'if'the shingles are not to be staggered,it is notnecessary to cut olf the up per corner, e,.the cuts in the corners f f,may

be made deeper and need not necessarily be 7o square, and the'main'requisite 'in-the cutting of the lower'corner, 'a', is that thefolded sides, F should not lap over. eachother. Our improved guttcr andfold may also be used.- wi th advantage for vertical seams, in which use libel-: oblique flange E may be dispensed With'fihough we would'recommend its use. We alsor'be' lieve that our device of adepressed-gutter will be found useful even where the fold f or otherprojecting edge of another shingle is not "So provided with a.downwardly-bent edge F/ though we prefer to useit in'this connection.
